      u32 CARD_GetResultCode(void);

## Description

This function returns the result of the last process that is run by the function that accesses the CARD ROM device and the backup device.

From the result value that is obtained with this function, the success or failure of the process and the detailed cause of the failure can be determined.

This function allows these functions to obtain the result value. However, the functions that are shown in green will always have a return value of `CARD_RESULT_SUCCESS`; therefore, it is not necessary to explicitly determine the value of the result.

These functions access the backup device:

#### [EEPROM]

CARD_ReadEeprom
CARD_ReadEepromAsync
CARD_WriteEeprom
CARD_WriteEepromAsync
CARD_VerifyEeprom
CARD_VerifyEepromAsync
CARD_WriteAndVerifyEeprom
CARD_WriteAndVerifyEepromAsync

#### [FLASH]

CARD_ReadFlash
CARD_ReadFlashAsync
CARD_WriteFlash
CARD_WriteFlashAsync
CARD_VerifyFlash
CARD_VerifyFlashAsync
CARD_WriteAndVerifyFlash
CARD_WriteAndVerifyFlashAsync

#### [Common]

CARD_IdentifyBackup
CARD_LockBackup
CARD_UnlockBackup

These functions access the ROM device:

CARD_LockRom
CARD_UnlockRom
CARD_ReadRomID
CARD_ReadRom
CARD_ReadRomAsync

Of the functions mentioned above, the result value of the last called function is the return value for this function. These return values do not change if functions other than the above mentioned CARD functions are called.

## Arguments
